Effect of ferromagnetic proximity on critical behavior
We have investigated the magnetic phase transition in amorphous Fe93Zr7(x Å)/Co95Zr5(1 Å) multilayers, where x = 25, 50, and 75. The extremely thin CoZr layer induces magnetic order at temperatures well above the inherent ordering temperature of Fe93Zr7. The changes in the critical exponent β, associated with the temperature dependence of themagnetization, imply a crossover from twoto three-dim...
متن کاملProximity effects in cold atom artificial graphene
Cold atoms in an optical lattice with brick-wall geometry have been used to mimic graphene, a two-dimensional material with characteristic Dirac excitations. Here we propose to bring such artificial graphene into the proximity of a second atomic layer with a square lattice geometry. For non-interacting fermions, we find that such bilayer system undergoes a phase transition from a graphene-like ...
متن کاملOrbital order induced ferromagnetic insulating properties
At temperatures below the metal–insulator transition of La1−xSrxMnO3 with 0.1 < x < 0.15, a peculiar ferromagnetic and insulating phase is observed which has been intensively discussed over the last few years. We present a detailed investigation of this phase by means of resonant and high energy x-ray scattering along with measurements of the electrical resistivity, thermal expansion, magnetiza...
متن کاملProximity effects induced in graphene by magnetic insulators: first-principles calculations on spin filtering and exchange-splitting gaps.
We report on first-principles calculations of spin-dependent properties in graphene induced by its interaction with a nearby magnetic insulator (europium oxide, EuO). The magnetic proximity effect results in spin polarization of graphene π orbitals by up to 24%, together with a large exchange-splitting band gap of about 36 meV. The position of the Dirac cone is further shown to depend strongly ...
